But now a legal challenge has been launched against the government for its implementation of the new tax on foreign buyers. A Vancouver law firm is looking to have a judge certify a class-action lawsuit against the B.C. Government and it's 15 percent tax on foreign buyers of homes in the Lower Mainland. Canadian legal experts maintain that the new foreign-buyers tax is a violation to the North American Free Trade Agreement by treating some investors in a discriminatory fashion.

It has also been argued that the new tax violates numerous other treaties that Canada has entered into as well. As well, Constitutional scholar Rocco Galati has also stated that the new tax is a violation of Section 15 of the Canadian Charter of Rights and Freedoms and he says that it prohibits discrimination based on race and national or ethnic origin.
